There is a way to solve the copy protection questions problem.
1. Make a copy of the 'Dune.exe' file. We are going to modify this file so it's a good idea to have a backup incase things go wrong.
2. Download a Hex editor. For this example i will be using the freeware program
XVI32.
3. Click 'File' then 'Open' and select the Dune executable ('Dune.exe').
4. Once it has opened click on 'Search' and then 'Find...'.
5. In the 'Hex string' box enter the following: 83 C4 08 0B C0 74 42
6. Click 'OK'.
7. 83 will now be highlighted. Move right until you reach 74.
8. Replace 74 with EB.
9. Save the file.
Now whenever you play the game you can type anything you want into the copy protection question screen and the game will assume it is the correct answer!!
Enjoy!!
